@@Mrich775 Yeah.... about that: They talked about that previously, and i already tried to do that at home, but the time and tools required to do that really outbalance the price of using a good lube (with wax in it, such as the MucOff HydroDynamic (developed with Team Sky)). And although this is a good lube, i don't usually use it, unless i'm preparing for a 100km ride or so. So, other than that, i just keep my chain clean with some WD-40 after each ride, and then use a little bit of MucOff/Motorex wet lube.
@@CyclingLifePT their video on it in the past was terrible honestly, go check out molten speedwax and their instructions on how to do so properly. My tech is just toss it in msw in my crock pot for 30mim to an hour then drip dry and reinstall. Simple as that.

Your comment made the difference between me waiting 20-30 seconds in, not hearing his response and clicking off of the video and actually fast forwarding and getting the answer.
For sore butts, dont forget that your stem height/bar reach and saddle angle play a role in how your weight is distributed across the bike. If your triceps and back feel fine but your butt is sore, try letting your upper body carry a bit more of the load.
As a 60 year old who started serious cycling in the early 80s, standard gears were what everyone used. I still have a standard chainset and tiny cassette on my 20 year old Casati aluminium road bike. When I got a carbon fibre Giant Defy in 2019 it practically rode itself. We were 'ard in my day.
This. Now cyclists spend more energy discussing couple of watts or expensive fidget spinners, instead of going out and putting same efforts into miles. These days 95% of bikes are light, durable and differ by nuances important for top level athletes, not most of amateurs.
If the equipment didn't change, people wouldn't have either because they didn't know any different. If you had modern gearing back then, you wouldn't think anything of it.
@Event 42 amateurs with money have always bought the best gear and that will always be true. Since the beginnings of Super Record and Dura Ace, pros were always a fraction of the population with those components.
Just on the lube frequency, I use rock n roll lube which cleans as your lube. I find with this type of lube its best applied every 2nd ride in dry conditions as it gets no build up.
I might point out that different lubes have different service lifetimes. I am using Morgan Blue touring. It has a light transport oil and a heavy grease type lube combined. The lighter components make the grease penetrate every part of the chain. The lighter ones evaporate or are thrown off. Leaving a relatively clean outside on the chain. But the inner surfaces can remain lubed for several thousand km of riding if it isn't raining. Lighter lubes create less drag but are thrown off more quickly. Good for racing but needs more regular attention. Choose what is right for your type of riding.
Re: The *@peter hedley* rear derailleur question - Like Ollie suggested, start from scratch INCLUDING *_to check that the RD is positioned correctly on your new RD hanger._* On my first new build I had the RD rotated back ~20 deg and the Di2 would not shift into the bottom two gears - one inept LBS charged me over $100 and could not troubleshoot this; a second one found it in five minutes.
Binyamin's q about saddle comfort - worth also noting that saddle discomfort might not be anything to do with the actual saddle. It could just as easily be down to bike fit. In fact I've heard some fitters say that while specific saddle models might be more or less comfortable for you, if you are experiencing serious discomfort it probably isn't the saddle causing it. It sounds like you could have too much weight on your saddle - and a bike fit could help you achieve a riding position that balances it more evenly across your contact points. A bike fit can be expensive, but is probably a better investment in the long run than buying lots of saddles.
I use Finish Line's Ceramic Wet Lube in rainy Thailand, even when its not raining because it lasts the longest of its products. Finish Line states one application will last 175 mi/280 Km for Ceramic Wet Lube but also notes that it takes 3 applications on a new chain to coat all of the surfaces with the ceramic material with 2 days between the initial applications. For Finish Line's Ceramic Wax Lube it states it will last 120 mi/190 km.
I only use dry lube for 12 months of the year in the UK. I don’t ride in the rain and clean my bike and re lube after every Winter ride. I absolutely love Muc-Off’s standard yellow top 4 step dry lube. It’s spotlessly clean and quick and easy to wash out after every WINTER ride. I’ve tried expensive waxes and all sorts of lubes but this £4 supermarket offering is my favourite
Derailleur needs the distance between the cassette and the upper derailleur pulley wheel adjusted. When the derailleur is to close to the cassette it may skip when you back pedal if the alignment is not perfect. Adding the longer cage means you need to make this adjustment.
Great advice on the saddle issue the user was having. A third possibility... I noticed as temps went from Summer to Autumn.. I had a habit of hydrating at intervals and I was the drinking same ammount at 12 degrees C as I was at 28. Needless to be said... I was racing like a piss horse!
An 11-34 11sp Shimano cassette needs the 1.8mm spacer as it's 10sp freewheel compatible. Fit that and everything should work as before without fiddling with the gear indexing
Agreed - no need to lube ever ride (in good conditions), but I DO wipe the chain off with a paper towel every time. Also, how about a video on how to match your position when you have two bikes e.g. winter and summer bikes?
Compact or standard cranks... Wouldn't it be a good idea to make a different combination? 52-36 for example? Changing one chainring would be the cheapest option to spread your gears. The gap between chainrings will get bigger but can be compensated with one or two clicks more at the rear.
@3:30 i think the guy might have threaded his new chain the wrong way over his rear derailleur cogs (jockey wheels).. I did this myelf and seems to skip over the metal bar that separates them.. scratched my head a few times and realised my error.. may be the solution?
really great vid and explanations Dr. Ollie! LOVED the saddle explanation. I've pulled expensive name brand saddles off my bikes to replace them with the $60 seat that seems to assist my poor hips perfectly. I seem to have missed that one tech show per the saddles though
A major reason for needing to pee every 5 minutes is all the coffee a lot of us are dependent on - it irritates your bladder and is a diuretic! The need for comfort breaks is also inversely proportional to the numbers of layers you are have to remove to go! (See ‘What to wear in winter vid’!)
Well before it squeaks there is a sort of a "rattling" sound that comes from the rollers. The oil serves as a cushion that dampens this noise. Once you hear the rattle there isn't much of a film between parts. Incidentally a clean steel chain often will not squeak even if bone dry. Tiny amounts of rust seem to really ramp up the squeaking sound.
#AskGCNTech Hi GCN, should you lube the pulleywheels once in a while when you are cleaning and lubing the chain or is this a bad idea? Different approached for cheramic ball bairing onces vs the bushing style?
To the questioner with a stuck blimit screw... If you have disk breaks be very careful when spraying the limiter screw as you'll contaminate your pads if you get any of that spray on it.
#askgcntech should I swap to wet lube if the forecast is for rain the next week (normally a very dry area), if so do I need to strip the chain clean with degreaser before applying the wet lube and then again to go back to the dry lube?
#askGCNTeck what are your thought about squirt chain wax. What happens when you do degrease your chain if you have used squirt wax? (it says you shouldn't). Is it the ideal all-season "lube"?
Squirt is great....lasts for several hundred kms, can survive wet conditions and leaves you with a nice clean chain. I have reapplied it to a degreased chain and its fine
#GCNTech how much should I lube my chain for the winters while I have a dedicated bike on my indoor trainer? Should I change to a dry lube while its inside and since there are no outside contaminants, what are general rules about how often to apply more lube?
I just came across this-- for indoor trainers, go with wax! It's so much cleaner and doesn't attract grime like wet/dry lubes tend to do (the science behind wet/dry lubes suggests that they clean themselves out by being used over distances- typically outside on the road/trails- so on a trainer, they just turn into mud bombs). My trainer drivetrain used to be a gross mess. Since I've been waxing, I first tried a drip wax and it worked fine... but I wanted to go all in, and am now using immersive hot melt. A wax based drip is still much better than any wet/dry lubes for this purpose by a country mile, so you don't have to go hot melt if you're not into the (minor) hassle.
Well ! I'm using OLIVE OIL to lube my chain. It's outstanding for reducing friction, to loose as few Watt's as possible. But the chain needs to bee cleaned, wiped completely dry and re-oiled after every ride. Olive oil doesn't handle water well for longer periodes, but most chain-oils doesn't, so... When chain-oils are being tested, mostly it's totally ignored how more or less hydofob/hydrofil the oils are and how it affects them.
After every ride (almost every) I wash the chain with soap and water and then lube it. This way I don't have to worry about the excess lube build-up and it's got fresh lube for every ride.
#AskGCNTech Hey! I’ve got Roval Rapide CLX wheels and recently put some Vittoria Corsa Control tyres on for winter. For my ~83kg weight, Roval recommends 89PSI whereas Vittoria recommends 125PSI. Generally, who should I be listening to-the wheel or the tyre manufacturer? Is it even usual for wheels to recommend a tyre pressure? And what might explain such a huge discrepancy between the two? TIA!
Hi, I have an external gear cable on my winter bike that is exposed (i.e. no outer cable) from the top of the down tube, through a BB guide, and to the end of the chainstay. I’d like to change it to a full outer cable. Are there conversion kits available for this that deal with the cable guides on the frame, or do I need to drill these through to enable a solid length of outer cable to run through? Also, do I need a new BB guide, or can I just zip tie it to keep it secure like brake cables are? Appreciate your help! #askgcntech
Why does my mech shift well in gear 1 thru 7, but 8-9-10 hesitate for two,or three pedal rotations before shifting. This happens whether big or small up front.
I just changed the cassette on my bike since my old one was a little worn, but when I got on my bike I could feel something clicking when pedaling especially in harder gears (i.e. it didn't feel smooth). According to my LBS the freehub needs replacement as it's no longer engaging properly. My question is, why did it seem perfectly fine on my old cassette? (I went from 8s 11-34 to 8s 11-32, but I don't think that difference is relevant) #askgcntech
#AskGCNTech Hi there. I have Ridley fenix 7005, alum frame, 105, and Mavic Acsium wheels and I love it, but what is better investment, new fancy wheels or sell bike and get carbon frame bike with average wheels? Thanks!
I'm looking to get set of Sram etap AXS derailleurs and shifters. Would I able to use a third party chain and chainset like a KMC 12-speed chain and a Rotor chainset? I think I've seen this done on bikes around instagram, but is it a bodge? My main motivation for doing this is a great price on the shifters/derailleurs, I'm not very attached to the design of the AXS chainset, and it would be an incredible spread of gears using 52-36 chainrings. #AskGCNTech
#AskGCNtech why not just use mineral oil? Is it too light? I’m thinking I’d rather run a little refresh of mineral oil which doesn’t seem to attract dirt and grit nearly as much as my Dumonde Tech Lite chain lube

Peter Hedley's question about the derailleur hanger could be that he had a longer derailleur hanger but replaced it with a standard one? They can be a nightmare to identify just the right one.
On the topic of lubing, I have waxed my chains for a while thinking that it is probably not just one of the best lubricants but also one of the most hardy. I recently played the part of a mobile drink station/domestique for my brother when he did his virtual London Marathon - the day was much wetter than expected and I ended up riding through some much deeper water (knee deep when stood up in the pedals and it was horrible flood water) than the 1" deep puddles/damp Berkshire weather I would usually tackle. It had completely killed my chain when I next got my bike out a couple of days later (I had hosed it off after) i.e. it had rust visible at the links and was noisy as hell - was it the wrong type of lube, poor application or just utterly stupid use of a bike? #AskGCNTech
I can’t find the question from the guy who experiences urinary frequency (or at least desire to pee with little result frequently) when riding. The solution suggested sounded good but the question was why. Diagram pasted after this but basically you are likely putting quite a bit of pressure on your urethra (see diagram) and soft tissue beneath your prostate and base of penis. Irritation of the urethra=desire to pee but nothing much there. Get the pressure off and it should improve. A number of us get milder versions of this in long rides. www.anatomynote.com/wp-content/uploads/2019/07/9523/Male-reproductive-system-anterior-view-and-lateral-view.jpg
#AskGCNTech I want to upgrade the cranks on my Grail CF SL to something lighter. I have noticed that MTB cranks are usually lighter. Can they be fitted to road bikes? Also I like the style of ALDHU cranks but Rotor has much lighter carbon MTB crank arms. They look like they would fit the road ALDHU axle, do they? Thanks!
Even if they fit, the q-factor is different (offset of the pedals, or how wide the distance between them is. Mtb-cranks have a larger q-factor for clearance, but smaller is better biomechanically iirc. So even if it fits, it might not be the best fit for your legs and knees especially
I've been worrying about how to remove those blackish oil build-up on my chain. I was able to wipe off most of it, but I knew, there are still left at the areas that only brushes can reach and also the rear derailleur cage. Are there other ways to clean the drivetrain without chain brush? #AskCGNTech
Dip it in lamp oil in a plastic bottle and shake vigorously. Let it sit for a while. Then do the same with dish soap and water. Rinse well with water and pat dry with a towel and a blower/hair dryer. Dip the chain in pure alcohol to dilute every last drop of water. It should evaporate quickly. Then put a drop of lube in every roller or give it a bath in molten wax.
#AskGCNTech - Hi GCN Tech. I want to fit Di2 to my Ribble Endurance SL. Do I need integrated bars to utilise the frames Di2 juntion box cut out on the down tube or will I have to use a bar end junction box? I can't work out how I would wire Di2 into the frame with my standard bar setup
#askgcntech Hey guys. My bottle cage threaded insert is loose, so the bolt just turns and doesn't loosen. Is there an easy way to remove these? Should I be using a specific glue to repair the insert? Thanks!
#askgcntech I have a 2010 SRAM red group set that the front derailleur will not stay in the big ring. When I swing the shifter, and hold it, it will go to the big ring, but when I let go, it immediately falls back to the small ring. I already checked the set screws, cable tension, cleaned all parts, including the shifter, but nothing worked. What could be causing this issue?
Ask GCN. Can you recommend a flat post mount hydraulic brake system for use with flat handlebars . My gravel bike has flat mounts for brakes but I use flat handle bars . I currently use cable brakes as can’t find anything suitable to upgrade 👍
#AskGCNtech why are most brakes lever setups are relatively opposites side one on the other. For example; If I were to setup my Cyclocross bike front brake is on my right hand side and my rear is on my left hand side as same with my mountain bike brake setup. Most brakes setups or built are setup the opposite of mine. My question, is their a specific reason to this or is it more of a personal preference?
BAH! A new rear derailleur hanger may need to be adjusted by bending it into the proper alignment based on what an alignment tool (such as the Park Tool Derailleur Hanger Alignment Gauge) shows in comparison the the rear wheel. This alignment should be checked periodically and especially after a crash that may have involved the rear derailleur.

#AskGCNTech Awesome content as ever! Anyway, as for my question: I recently pulled the trigger on a pair of Zipp 303s for my gravel bike to have a "road mode".

No, SRAM Road 12-speed has its own gearing configuration. The chain rollers on SRAM Road 12-speed chains are larger than other chains', so it won't allow for full chain and teeth engagement.

Hi, #AskGCNTech, I use rollers (tacx galaxia) for my indoor training but I start to dislike that I need to concentrate every second to not fall off. I don't fancy buying a new set of indoor trainers, but I've come across a 'bike support front wheel mount' specific for my rollers. Does this compromise the feeling of the bike? Is it just a safety measure or can you use this wheel mount to 'zone out' (like I would want to). Thanking you in advance. Keep up the nice videos!

Ollie, how often would you recommend oiling your chain it you have it on the trainer all winter with no outdoor riding? #askGCNTech
when you can hear it.
Call me old fashioned but I always oil my chain before it starts squeaking 👍🏻
How do you know it’s before it’s going to start squeaking? Crystal ball?
@@grobbosixtyone Pay attention to how quietly the chain is running and how easily it is shifting. Be in tune with your machine. It's not a black box.
Well before it squeaks there is a sort of a "rattling" sound that comes from the rollers. The oil serves as a cushion that dampens this noise. Once you hear the rattle there isn't much of a film between parts. Incidentally a clean steel chain often will not squeak even if bone dry. Tiny amounts of rust seem to really ramp up the squeaking sound.

Just wax the chain, 500g wax plus 50g ptfe powder melted. Dip a really clean chain into the wax and you are good for300miles
To the questioner with a stuck blimit screw... If you have disk breaks be very careful when spraying the limiter screw as you'll contaminate your pads if you get any of that spray on it.
#askgcntech should I swap to wet lube if the forecast is for rain the next week (normally a very dry area), if so do I need to strip the chain clean with degreaser before applying the wet lube and then again to go back to the dry lube?
#askGCNTeck what are your thought about squirt chain wax. What happens when you do degrease your chain if you have used squirt wax? (it says you shouldn't). Is it the ideal all-season "lube"?
Squirt is great....lasts for several hundred kms, can survive wet conditions and leaves you with a nice clean chain. I have reapplied it to a degreased chain and its fine
#GCNTech how much should I lube my chain for the winters while I have a dedicated bike on my indoor trainer? Should I change to a dry lube while its inside and since there are no outside contaminants, what are general rules about how often to apply more lube?
I just came across this-- for indoor trainers, go with wax! It's so much cleaner and doesn't attract grime like wet/dry lubes tend to do (the science behind wet/dry lubes suggests that they clean themselves out by being used over distances- typically outside on the road/trails- so on a trainer, they just turn into mud bombs). My trainer drivetrain used to be a gross mess.
Since I've been waxing, I first tried a drip wax and it worked fine... but I wanted to go all in, and am now using immersive hot melt.
A wax based drip is still much better than any wet/dry lubes for this purpose by a country mile, so you don't have to go hot melt if you're not into the (minor) hassle.
Well !
I'm using OLIVE OIL to lube my chain.
It's outstanding for reducing friction, to loose as few Watt's as possible.
But the chain needs to bee cleaned, wiped completely dry and re-oiled after every ride.
Olive oil doesn't handle water well for longer periodes, but most chain-oils doesn't, so...
When chain-oils are being tested, mostly it's totally ignored how more or less hydofob/hydrofil the oils are and how it affects them.
My mate runs a 53-34 and it works perfectly
Back in the day the standard was 52/42 not 53/39 as you reckon!
Or 53/42 as it is on my old Nuevo Record crankset
Yes, I do remember that as standard back in the 10-speed days. But for these hosts, "back in the day" is more like year 2000.
After every ride (almost every) I wash the chain with soap and water and then lube it. This way I don't have to worry about the excess lube build-up and it's got fresh lube for every ride.
#AskGCNTech Hey! I’ve got Roval Rapide CLX wheels and recently put some Vittoria Corsa Control tyres on for winter. For my ~83kg weight, Roval recommends 89PSI whereas Vittoria recommends 125PSI. Generally, who should I be listening to-the wheel or the tyre manufacturer? Is it even usual for wheels to recommend a tyre pressure? And what might explain such a huge discrepancy between the two? TIA!
#askgcntech. Touch up paint, Where can you buy the same exact paint that was used on your bike?
Hi, I have an external gear cable on my winter bike that is exposed (i.e. no outer cable) from the top of the down tube, through a BB guide, and to the end of the chainstay. I’d like to change it to a full outer cable. Are there conversion kits available for this that deal with the cable guides on the frame, or do I need to drill these through to enable a solid length of outer cable to run through? Also, do I need a new BB guide, or can I just zip tie it to keep it secure like brake cables are? Appreciate your help! #askgcntech
Why does my mech shift well in gear 1 thru 7, but 8-9-10 hesitate for two,or three pedal rotations before shifting. This happens whether big or small up front.
4:16 "binnie amin" ollie are you serious lmao
I just changed the cassette on my bike since my old one was a little worn, but when I got on my bike I could feel something clicking when pedaling especially in harder gears (i.e. it didn't feel smooth). According to my LBS the freehub needs replacement as it's no longer engaging properly. My question is, why did it seem perfectly fine on my old cassette? (I went from 8s 11-34 to 8s 11-32, but I don't think that difference is relevant) #askgcntech
#AskGCNTech Hi there. I have Ridley fenix 7005, alum frame, 105, and Mavic Acsium wheels and I love it, but what is better investment, new fancy wheels or sell bike and get carbon frame bike with average wheels? Thanks!
Anything wrong w/ silicone spray in cable housing?
#AskGCNTech Hi Ollie, can I use motorcycle chain cleaner and chain lube on my bicycle? will there be any adverse effects?
I'm looking to get set of Sram etap AXS derailleurs and shifters. Would I able to use a third party chain and chainset like a KMC 12-speed chain and a Rotor chainset? I think I've seen this done on bikes around instagram, but is it a bodge? My main motivation for doing this is a great price on the shifters/derailleurs, I'm not very attached to the design of the AXS chainset, and it would be an incredible spread of gears using 52-36 chainrings. #AskGCNTech
#AskGCNtech why not just use mineral oil? Is it too light? I’m thinking I’d rather run a little refresh of mineral oil which doesn’t seem to attract dirt and grit nearly as much as my Dumonde Tech Lite chain lube
I have an alloy road bike frame and I want to change my alloy seatpost to carbon seatpost. Do I need to put carbon paste on the carbon seatpost? #AskGCNTech
Can you make a how to video on replacing and setting up a new saddle please? #askgcntech
I am planning to replaced my original long OEM flat saddle with a new short saddle with the back slightly curving up
After severe service which includes dirt or wet.
Peter Hedley's question about the derailleur hanger could be that he had a longer derailleur hanger but replaced it with a standard one? They can be a nightmare to identify just the right one.
On the topic of lubing, I have waxed my chains for a while thinking that it is probably not just one of the best lubricants but also one of the most hardy. I recently played the part of a mobile drink station/domestique for my brother when he did his virtual London Marathon - the day was much wetter than expected and I ended up riding through some much deeper water (knee deep when stood up in the pedals and it was horrible flood water) than the 1" deep puddles/damp Berkshire weather I would usually tackle. It had completely killed my chain when I next got my bike out a couple of days later (I had hosed it off after) i.e. it had rust visible at the links and was noisy as hell - was it the wrong type of lube, poor application or just utterly stupid use of a bike? #AskGCNTech
I can’t find the question from the guy who experiences urinary frequency (or at least desire to pee with little result frequently) when riding. The solution suggested sounded good but the question was why. Diagram pasted after this but basically you are likely putting quite a bit of pressure on your urethra (see diagram) and soft tissue beneath your prostate and base of penis. Irritation of the urethra=desire to pee but nothing much there. Get the pressure off and it should improve. A number of us get milder versions of this in long rides. www.anatomynote.com/wp-content/uploads/2019/07/9523/Male-reproductive-system-anterior-view-and-lateral-view.jpg
#AskGCNTech I want to upgrade the cranks on my Grail CF SL to something lighter. I have noticed that MTB cranks are usually lighter. Can they be fitted to road bikes? Also I like the style of ALDHU cranks but Rotor has much lighter carbon MTB crank arms. They look like they would fit the road ALDHU axle, do they? Thanks!
Even if they fit, the q-factor is different (offset of the pedals, or how wide the distance between them is.
Mtb-cranks have a larger q-factor for clearance, but smaller is better biomechanically iirc.
So even if it fits, it might not be the best fit for your legs and knees especially
I've been worrying about how to remove those blackish oil build-up on my chain. I was able to wipe off most of it, but I knew, there are still left at the areas that only brushes can reach and also the rear derailleur cage.
Are there other ways to clean the drivetrain without chain brush? #AskCGNTech
Dip it in lamp oil in a plastic bottle and shake vigorously. Let it sit for a while. Then do the same with dish soap and water. Rinse well with water and pat dry with a towel and a blower/hair dryer. Dip the chain in pure alcohol to dilute every last drop of water. It should evaporate quickly. Then put a drop of lube in every roller or give it a bath in molten wax.
#AskGCNTech I have recently bought a Defy ADV1 with tubeless tyres. What tubeless specific spares should I carry - can I dump the inner tube?
Hi Ollie, What do you do when you have a bolt that is already seized and you can't loosen it?
Thanks in advance,

Great video
#AskGCNTech - Hi GCN Tech. I want to fit Di2 to my Ribble Endurance SL. Do I need integrated bars to utilise the frames Di2 juntion box cut out on the down tube or will I have to use a bar end junction box? I can't work out how I would wire Di2 into the frame with my standard bar setup
Sounds like the the guy with the saddle problem needs a, everything down and forward saddle adjustment to me. Oh! And the Salle Italia Novus is nice!
Might also need a cutaway depending on his position
Yeah, I like the Selle Italia Novus in all positions, I prefer the drops. Its also nice riding in my cruise position.
Agree. Why didn’t Ollie suggest tilting it down a fraction. 🤔 Sell another saddle!
@@hisdadjames4876 Possibly because tilting it down might create new problems. Really the dude needs a bike fit
#askgcntech Hey guys. My bottle cage threaded insert is loose, so the bolt just turns and doesn't loosen. Is there an easy way to remove these? Should I be using a specific glue to repair the insert? Thanks!
#askgcntech I have a 2010 SRAM red group set that the front derailleur will not stay in the big ring. When I swing the shifter, and hold it, it will go to the big ring, but when I let go, it immediately falls back to the small ring. I already checked the set screws, cable tension, cleaned all parts, including the shifter, but nothing worked. What could be causing this issue?
Ask GCN.
Can you recommend a flat post mount hydraulic brake system for use with flat handlebars . My gravel bike has flat mounts for brakes but I use flat handle bars . I currently use cable brakes as can’t find anything suitable to upgrade 👍
Maybe take a look at the mountainbike hydraulic brakes those are made for flat bars.
@@simonderoo9189 yes but they are post mounts not flat 👍
#AskGCNtech why are most brakes lever setups are relatively opposites side one on the other. For example; If I were to setup my Cyclocross bike front brake is on my right hand side and my rear is on my left hand side as same with my mountain bike brake setup. Most brakes setups or built are setup the opposite of mine.
My question, is their a specific reason to this or is it more of a personal preference?
#AskGCNTech Hi! I have to disconnect my discbrake hoses while changing my handlebar. Do i need to bleed brakes? Do i need to replace the olives?
Yes. No
BAH! A new rear derailleur hanger may need to be adjusted by bending it into the proper alignment based on what an alignment tool (such as the Park Tool Derailleur Hanger Alignment Gauge) shows in comparison the the rear wheel. This alignment should be checked periodically and especially after a crash that may have involved the rear derailleur.
* Editors note addendum - this is also an insight into why Ollie presented in a one person flat during lockdown and includes references in scripts to behaviour "likely to annoy your mum" rather than partner/wife :-)
You know, I kind of figure if a man doesn't know not to do this yet, they've never had a serious LTR.
#AskGCNTech I have changed my crank arm length from 172.5 to 165 Do I need to lift my saddle? If yes, how much? Thank you.
#AskGCNTech Awesome content as ever! Anyway, as for my question:
I recently pulled the trigger on a pair of Zipp 303s for my gravel bike to have a "road mode". Whenever the heavens open, as you it does during this time of year (Thank you Scotland), my wheels seem to collect water inside it. Whats the most efficient way of draining it? or to prevent it from seeping in to begin with? Thanks very much!
@7:55 Did you just say that, without giggling? 🤭
After ride bike, how to desinfic my tyres and bike before take him in my flat?

#aASKGCNTECH:This is my First time asking Question. I have a gtr mountain bike and whenever I put the left gear in 1 and the right gear in let's say 3 or 5 the rim brakes are running on my Tire. Do I just need to move the brake pads down or is that a serious problem that needs to be fixed at a bike shop? Would love to hear what you guys recommend
Lube, penetration, screw? What am I watching doc Ollie? 🤣✌🏼
#askgcntech henlo fren! i've recently swapped my stock stem out for a much shorter one for a better fit on my bike. i'm now looking to trim my shift cables and hydraulic lines to tidy up the cockpit. i'm soon to be ordering the parts and tools to perform the operation. my question is, do i need dedicated hose cutters or can the cable cutters in my amazon cart double as hydraulic hose cutters, thereby saving me 25 bucks on what would otherwise be a one time use tool? thanks! 🤙🤙
#AskGCNTech My bike has mechanical disc brakes and the rotor is rubbing with the outside pad and I cant adjust that one. Is my Rotor bent or is there a method to fix it, btw i have watched your video on how to calibrate the mechanical disc brake caliper. Thank you so much

#askGCNtech I'm using SRAM red Axs 10-33t with Crankset 48/35t, I feel this not suit my riding style... I wish to replace wish standard Crankset 53/39t from Shimano... It is works or compatible on SRAM AXS drive train systems?
No, SRAM Road 12-speed has its own gearing configuration. The chain rollers on SRAM Road 12-speed chains are larger than other chains', so it won't allow for full chain and teeth engagement.
#AskGCNTeck I bought a 2020 scott road bike and it weighs a pound heavyer then the exact same 2013 model i have, I would like to understand how this makes any sense?
I lube it every ride, but i only do dry wax even in moist conditions. I hate the dirty black gunk from wet lubes.
#AskGCNTech My son would like to try zwifting and has his own bike. Problem is that it's 24 inch and has a 7 speed with a big chain. I would like to let him use my elite suito with the Shimano 105 11 cassette.
Any suggestions on how to approach this?
Hahahahahahahahahahahaha!!!! 3:31 this is Africa! Lmao, love it
O man I maintain my tires make sure they're nice and fat with air. But when it comes to my chain ooooooo I'm a bad rider ! Ha ha ha ha ha. I would let my chain get black goo up till I have a god day off to take 10-15 minutes to clean it up.
My baa question is if my chain is tad bit loose dose that make it worse or ok ? As far as maintaining it ?
#AskGCNTech I’ve recently bought a Wahoo Kickr for the winter & I’ve noticed I’m really uncomfortable on my saddle (numbness/tingling sensation) when I’m using it. This doesn’t happen when I ride out on the roads. The bike, my saddle height, bib shorts and shoes/pedals don’t change between uses. Any ideas as to what is wrong? Thanks!
#AskGCNTech Have Shimano SPD mnt bike style cleats. On different bikes with different pedals, I get an annoying squeaking. Sounds like a creaking BB, but does it on different bikes with different BB types, so something to do with the cleats/shoes. Any suggestions?
Try a small drop of oil underneath the front tip of the cleat (the side facing the sole). It will also make engagement and disengagement easier.
#AskGCNTech In a previous episode you mentioned that when a bike is put into a bike stand, it should be clamped via the seat tube since the seat tube is designed for compression and the top tube is not. Does this mean sitting on the top tube could damage the bike?
#AskGCNTech hi! Have a dilemma, I ride a focus izalco race 105 al 2018 and got a old madone 4.7 from 2010 ultegra. Real first world problem but which frame is better? Should I build the madone with new parts? Thanks!
Good question Niels, we've found that lower ranged components which are more modern can often have better performance, but that's completely up to you

Hi, #AskGCNTech, I use rollers (tacx galaxia) for my indoor training but I start to dislike that I need to concentrate every second to not fall off. I don't fancy buying a new set of indoor trainers, but I've come across a 'bike support front wheel mount' specific for my rollers. Does this compromise the feeling of the bike? Is it just a safety measure or can you use this wheel mount to 'zone out' (like I would want to). Thanking you in advance. Keep up the nice videos!
Are you sponsored by Muc-Off, or do you just rate it so highly that that is what you recommend using, you are always showing or mentioning it? I really would like to know, I use it but want to know if it really does live up to the hype
Get your wife an ELECTRIC bike. She will be able to keep up with you on rides, you absolute beast.
That's really great advice! Although my hubby is now considering getting himself an e-bike...while I ride an old school mtb.
